v1.1 polish: accessibility, error logging, localization, and code quality sweep

- Wrap 30+ production print() statements in #if DEBUG guards across 18 files
- Add VoiceOver labels, hints, and traits to Watch app, Live Activities, widgets
- Add .accessibilityAddTraits(.isButton) to 15+ onTapGesture views
- Add text alternatives for color-only indicators (progress dots, mood circles)
- Localize raw string literals in NoteEditorView, EntryDetailView, widgets
- Replace 25+ silent try? with do/catch + AppLogger error logging
- Replace hardcoded font sizes with semantic Dynamic Type fonts
- Fix FIXME in IconPickerView (log icon change errors)
- Extract magic animation delays to named constants across 8 files
- Add widget empty state "Log your first mood!" messaging
- Hide decorative images from VoiceOver, add labels to ColorPickers
- Remove stale TODO in Color+Codable (alpha change deferred for migration)
